A multi-spur, 2-wing, and 3-wing bits are specialized drill bits designed for drilling clean holes in wood and are commonly used for tasks like installing door locks. These bits feature a sharp centering point and multiple cutting spurs that create a fast, aggressive cut, often lifting chips out of the hole, which can result in a flat-bottomed hole similar to a Forstner bit. Generally speaking, 2-wing and 3-wing offer a great, fast cut for industrial uses. Multi-spur bits will move slightly slower but will offer an even finer finish. 

Comsurge Tooling offers a wide variety of 2-wing, 3-wing, and multi-spur bits, including a variety of lengths, diameters, and both high-speed steel and carbide-tipped constructions.
